To all whom t may Concern.

lBe it known that I, PHILIP W. MOORE, a citizen of the United States, residing at Evanston, in the county of Cook and State of Illinois, have invented certain new and useful'Improvements in Rail-Stays, of which the following is a specification.

My invention relates to a rail stay, that is, to a device for checking the tendency of a railroad rail to creep longitudinally, and the invention consists in the novel improvements, constructions and arrangements which will be hereinafter described and claimed.

The invention contemplates particularly a rail stay of the wedge type, that is, comprising two elements having a wedging relation with respect to each other and the rail, one of which elements bears against the tie and the other stands away from the tie and is driven toward the same so as to give the necessary gripping action.

An important object of the invention is to provide a rail stay of this type in which the free member may be driven toward the tie, in applying the device to the rail, without the twisting or skewing of the parts of the device on the rail which is very likely to occur with many rail stays of the wedge tvue and which, when it takes place, makes the hold of the device on the rail insecure and ineffectual. s

A`fI1rther object of the invention is to providel a rail stay, of the wedge type, in which the area of contact between the engaging'elements and the configuration of the engaging parts of said elements is such as to produce a very considerable friction, re-

sisting tie tendency of said elements to become loosened from vibration or other causes.

A further object of the invention is to so construct theelements constituting the device that the free element, that is, the one out" of contact with the tie, will be guided onthe stationary element, when it is driven Vinto place or moves with the rail, by two separated pairs of wedges in parallel arrangement, whereby a firmgrip of the de.

vice on the rail is produced which very materially enhances the efficiency of the device in checking the creeping tendency of the rail.

A further object of the invention isto provide a rail stay which will be compact, light, strong, cheap to manufacture, and which may be quickly and conveniently applied to the device may be conveniently` applied to a rail which has near it a guard rail so that the amount of free space at the side of the base flange of the rail to which the device 1s to be applied is considerably restricted; although it will be understood that rail stays constructed in accordance with the invention are not limited in their use to this particular situation. The dra-wings appended hereto show the invention embodied in a preferred construction.

Figure 1 is a view, in elevation, showing ythe rail stay applied to a railroad rail adjacent to which is arranged a guard rail, the rails being illustrated in cross section. Fig. 2 .is a sectional plan taken on line 2 2 of Fig. 1. Fig. 3 is a vertical sectional view on line 8-3 of Fig. 2, and Figs. 4: and 5 are perspective views of the two elements constituting the rail stay, certain portions of the element shown in Fig. 5 being broken away so as to better illustrate the constructioniof this element of the device.

i Like characters of reference designate like parts in the several figures of the drawings. Referring to the drawings, A designates a railroad rail, B one of the cross ties supporting the same, and C a guard rail adjacent rail A, the base flange D of whichis cut off on one side in accordance with the usual practice.

' The rail stay consists, in the preferred construction shown, of a stationary element E and a movable element F. The stationary' element E is provided with a flange or plate G adapted to bear against the tie B and with a jaw H adapted to extend around one, edge of the base flange of the rail. This jaw comprises a plate or base member I which bears against the under surface of the base flange of the rail. The movable element F comprises a bar or base member J which extends under and is in Contact with the base flange of the rail, a jaw K which engages one edge of said base fiange, and a largerv jaw L adapted to extend around the jaw H of the stationary member. These two jaws are tapered as shown so that the forportion of the movable member is cut away at one end so as to provide a recess M to receive the plate or base portion I of the stationary` member. is formed on its under side with a tongue N which projects under and engages a tongue O on the stationary member G; These tongues are formed with coengagingwwedgying surfaces in parallelism with thel wedgl ing surfaces on the jaws H and L.

n applying the device to a rail thel stationary member is placed on the rail with its tie abutting fiange against one of the cross ties. The other member is then put in place on therail with its jaw K surrounding one edge of the base fiangeof said rail and the other jaw L surrounding the jaw H on the first named element. The movable element is then driven toward the tie until a gripping action of the required intimacy is obtained. This will ordinarily be done by striking jaw L with a hammer or maul. If this causes either part of the anchor to. twist or skew on the rail base, this may be corrected by striking the driven member on the other. end, `that is, on the jaw K. The device is an improvement on the wedge type rail stays having a single pair of co-engaging wedge members. In

such devices the driven element is accessible.

only at one end. Hence therepis danger that the parts of the device may become twisted in driving up the drivenelement and the hold on the rail thereby impaired. It will be Seen that jaw K, being relatively small, the device may easily be applied to a rail even thoughk there is a guard rail located.

close thereto. The elements are provided with two pairs of wedge members or faces in parallelism with each other. cumstance'increases the frictional grip of one element on the other so' as to minimize the danger of the device being loosened in its grip because of the vibration of the rail, or other causes. Any tendency of the rail to creep is self checked since the forward movement of the railv involves a forward movement of the movable element F and this tightens the lateral gripiof the device on the rail base; an effect which is enhanced by the fact that the movable element, guided on the stationary element by the.` two pairs of coperating wedge surfaces, is compelled to move forward bodily instead of twisting or rocking as might happen if aV single wedge engagement were provided between said elements.
